Re: [hylafax-users] Problem Receiving Faxes

Hi Lee,

Thanks for the prompt response. I have updated to HylaFAX+ 5.1.3 and my initial tests look good (no errors :)). I appreciate your help with this.

One additional question: Do you have any recommendations for an internal modem that will send a DID or do you know of a way I can get my current modems to get the DID?

Thanks again for the above fix. I will let you know if the problems occurs again.

I am have been running hylafax for years now on my Mandrake Linux 10.1
system.  It has 3 - MultiTech (LT V.92 1.0 MT5634ZPX-PCI-U Internal
Data/Fax/Voice Modem Version 1.32i) modems.  We use them for receiving
only and they are configured for class 1.0.

The problem it that occasionally we recieve faxes that give "MODEM No
carrier" messages.  The messages seem to originate from the same fax
machines and those fax machines return "Poor Line Quality" messages.


The session log below indicates that the sender does not like to hear CRP from you during Phase B. You should have a better time if you install HylaFAX+ 5.1.3. (http://hylafax.sourceforge.net). Please do add "Class1HasRHConnectBug: yes" to your modem config file since it does apply to your modems.

HylaFAX+ doesn't send CRP in Phase B any more - and PLUS has the workaround that you would have needed in the given log to have recovered before even wanting to send CRP in the first place.

I have tried to fix this by adding "Class1ECMFrameSize:     64" to the
config file but it doesn't help.


Please don't mess with Class1ECMFrameSize unless you really know what it is you're doing. It changes the preference that the Class 1 ECM driver has - against 256 bytes and to the much less-popular 64 byte version that may not be well-supported.

Thanks,

Lee.
